Local Planning Authority Green Belt: England 2018/19
England has a land area of just over 13,046,130 hectares (according to the Office for National Statistics mean high-water mark1). Of this area only about 8 per cent is of developed use.
Allowing for overlaps, just over 40 per cent of the area of England (5.6 million hectares) is protected against development by one or more environmentally-protected designations. As well as designated Green Belt land, this estimate covers National Parks, Areas of Outstanding Natural Beauty (AONBs) and Sites of Special Scientific Interest (SSSIs)
The extent of the designated Green Belt in England as at 31 March 2019 was estimated at 1,621,150 hectares, around 12.4% of the land area of England.
Overall there was a decrease of 3,290 hectares (0.2%) in the area of Green Belt between 31 March 2018 and 31 March 2019.
In 2018/19, thirteen local planning authorities adopted new plans, with the result being a net decrease in the overall area of Green Belt compared to 31 March 2018.
